Re: [dpdk-dev] [EXT] [PATCH 04/10] crypto/octeontx: fix global variable multiple definitions

[Anoob Joseph <anoobj@marvell.com>]

Hi Ferruh,

This patch could be problematic as our new PMD(crypto_octeontx2) also makes use of some of these. I will propose a new patch with the required changes so that you wouldn't see the mentioned issue. Does that sound ok?

Thanks,
Anoob
